Adventures of a Summer Student

Adventures of a Summer Student

Posted on: Monday September 28, 2015

As a child, the Manitoba Museum was my favourite field trip destination. I loved it all, but my favourite part was the Urban Gallery- particularly Madame Taro’s small apartment, which I thought was quite glamorous. Visits to the museum— either with classmates or family— activated my interest in history and museum work, and this summer I was given the opportunity to join the team through the Young Canada Works program as Collections and Conservation Assistant.

Summer student Jenna smiles towards the camera from her seat at a desk and computer.

One of the first projects I took on was identifying locations for human history artifacts whose locations are “unknown” in the database – 527 artefacts, to be exact. It could be summed up as a glorified treasure hunt. I spent a good few weeks going through the human history storage room— climbing up ladders, rifling through drawers, looking for catalogue numbers on hundreds of artifacts— and finally whittled the number down to 188! This was certainly one of my favourite projects of the summer. It was really fascinating to explore the variety of objects in the collection – everything from night caps to an Oh Henry bar package.

Throughout the summer I performed various forms of preventive conservation. At the end of each month I went through the galleries, labs, and storage vaults throughout the museum to take temperature and humidity measurements, as well as check the bug traps (yikes!). In August, a few of us went down into the hold of the Nonsuch to take taper gauge and trammel rod measurements to determine if the wood of the ship had expanded or contracted in the last six months. Even being on the ship for a couple hours felt a bit claustrophobic – I can’t imagine sailing for months at a time! In addition to these larger projects, I made boxes, altered mannequin forms, and recovered the bales in the Nonsuch gallery. The skills I had learned in 8th grade Home Economics finally paid off.

Perhaps one of the coolest things I did this summer was make a replica of a felt pennant for the upcoming “Nice Women Don’t Want the Vote” exhibit (which potentially thousands of people will see – no pressure!). Because the original artifact is quite worn and faded, a replica is more suitable to send along with the travelling exhibit to prevent further damage. Although I was a bit concerned about my lack of sewing and crafting skills, I am incredibly happy with and proud of the final product. The theme of the exhibit—women’s suffrage in the early 20th century—has been an interest of mine for quite a few years, and to be involved in the exhibit in any way was really incredible.

I had a great time at the museum this summer and was able to work on projects in many different areas of collections and conservation. The skills I built on and developed will no doubt open more opportunities for me in my (hopefully) museum-based future. The entire experience—the work and the people—was incredible, and I hope to be back here in the future!

Craziest Botanical Explorers in History

Posted on by Diana Bizecki Robson
Posted on: Monday September 28, 2015

As the opening of the National Geographic Presents: Earth Explorers exhibit at the Museum draws near, I find myself remembering some of the botanical explorers I learned about when I was a student. Although these botanists lived at different points in time they shared one thing: an insane passion for plants that very nearly caused their demise!

Sir Joseph Banks, 1743-1820

A line engraving of a man in profile, with his long hair tied back with a ribbon. Engraved text under the photo reads, "Mr. Bankes".

After whetting his appetite for botanizing in Newfoundland and Labrador, Banks manipulated his way onto the Endeavour, a ship captained by none other than James Cook. During this voyage Banks collected plants from South America, Australia, and New Zealand, contracted malaria, nearly died from exposure and lost four companions. While planning a second journey to search for Antarctica, Banks insisted on bringing 15 companions with him including two horn players (cause everyone knows you just can’t botanize without horn players following you around). To accommodate them, he had a second deck built on the ship Resolution, which made it too top heavy to be seaworthy. Captain Cook was not amused and had it torn down. When Banks saw that his new deck was gone, he had an “epic” tantrum worthy of a spoiled two year old and refused to sail, going on a trip to Iceland instead!

David Douglas, 1799-1834

Four cones from a Douglas-fir on a grey surface.

This irascible Scot was a true botanical nutcase. The son of a stonemason, Mr. Douglas became friends with renowned botanist William Hooker, who sent him on a plant collecting trip to the United States in 1823. Instead of bringing food, Douglas had his horse carry 100 pounds of paper to press plants in instead. This turned out to be a bad idea; he was reduced to eating all the berries, roots, and seeds he had collected on several occasions and was twice “obliged to eat up his horse” so that he wouldn’t starve to death. He nearly died from hypothermia, infections, falling into a gully, being attacked by grizzly bears, and the list goes on. The magnificent and enormous Douglas-fir trees (Pseudotsuga menziesii) of the west coast were named after him. He fell into a pit and was gored to death by the bull that was inside it at the age of 35.

Benedict Roezl, 1823-1885

A hand-drawn picture of a 'Miltoniopsis roezlii' orchid - white petals with a red and yellow interior, and long green leaves.

This hearty Czech botanist was obsessed with collecting orchids, discovering 8oo new species from the Americas. He was so obsessed with orchids that he once climbed a 5,000-m high mountain in Peru looking for new species, despite the fact that he had only one arm (the other was a prosthetic with an iron hook on the tip). To thwart competing orchid hunters, Roezl would either collect or destroy the rarest species he found, to the chagrin of conservationists everywhere. He was robbed by bandits 17 times but fortunately never lost much because the only things he carried were plants. Disappointed at the prospect of no money, one group of exasperated thieves was inclined to cut his throat. They spared him because he was clearly crazy (why would a one armed man wander around the countryside collecting weeds?), and believed that it was bad luck to kill a crazy person.

John Macoun, 1831-1920

Three pressed preserved plants on a sheet of specimen paper. At the end of each of the long, thin stems is a small blue-purple flower. In the bottom right corner specimen data is noted.

Offered the chance to explore the wild west of Canada during a railroad route reconnaissance, Mr. Macoun jumped at the chance, despite the fact that he didn’t know how to swim, canoe, snowshoe, drive a dog sleigh, or even ride a horse very well. He left a pregnant wife and four children behind during his first trip from Ottawa to Victoria in 1872. His journeys to collect the west’s flora occasionally met with disaster. He nearly drowned, was almost crushed by two falling trees, and accidentally shot off his thumb. During one journey, too weak from lack of food to row his canoe upstream, he tied a rope around his waist so he could pull it while stumbling along the shore instead. He collapsed from exhaustion close enough to his destination that he was rescued by local First Nations people. Despite these hardships Macoun collected an astounding 100,000 plant specimens in his lifetime.

Richard Evans Schultes, 1915-2001

A black and white photograph of Dr. Richard Evan Schultes with two Indigenous people in the Amazon. He is holding a selection of plants.

Schultes was obsessed with plants in a slightly different way than the others; he studied the medicinal and hallucinogenic ones. He wrote his undergraduate thesis on peyote and his Ph.D. on magic mushrooms. Not one to take someone’s word on the effects of hallucinogenic plants, he tried many himself, one time passing out for three days. He also took up the indigenous habit of chewing coca leaves to stay alert while travelling in the rainforests of South America. Once, he accidentally set fire to his collection while desperately trying to dry his plants in the jungle, nearly burning down his hosts’ house in the process. Schultes almost died from malaria, the nutritional disorder beriberi, and nearly drowned while doing field work. One night five vampire bats sat on his head and drank his blood. A grateful entomologist he once travelled with named a cockroach genus after him (Shultesia). He collected over 24,000 plants including 300 new to science and is considered the father of ethnobotany.

Cleaning Week: Filing Trilos

Posted on by Rebecca Watson
Posted on: Wednesday September 23, 2015

By Dr. Graham Young, Curator Emeritus of Geology and Paleontology

 

Last week was the Museum’s “cleaning week”, during which we were closed to the public so that we could focus on getting our house in order. There was much recycling of paper, moving of old furniture, and scrubbing of walls in many parts of the Museum. Here in the Geology and Paleontology lab, we decided that this was the ideal time to file some of the fossils that had been catalogued in the past few months. Most particularly, we put away several hundred Ordovician age trilobites from the Stony Mountain Formation at Stony Mountain, just north of Winnipeg.

Three drawer inserts full of catalogued trilobites, ready to be placed into their drawers.

How did the Museum end up with hundreds of trilobites that needed cataloguing? Stony Mountain is one of the really important sites in southern Manitoba dating from the Late Ordovician Period, about 445-450 million years ago. During this time central North America was covered by tropical seas, and at Stony Mountain the limestone deposits are tremendously rich in fossils of marine invertebrates: corals, brachiopods (lamp shells), trilobites, and many other kinds of creatures.

 

Image: Some of the catalogued trilobites, ready to be filed away.

Close up on a small box with six fossil pieces laid in cut-out foam beds, and a vial with cotton and smaller fossil pieces.

Staff and volunteers from this Museum and its predecessor have collected fossils at Stony Mountain since the 1930s; over the years thousands of specimens have been catalogued to our collections, but very few of these were trilobites. A museum always collects more samples than can be catalogued quickly, and the Stony Mountain trilobites are somewhat complicated and consist mostly of small pieces*, so we had been holding onto them until there was time to consider which ones belonged in the permanent collection.

 

Image: Components of a trilobite that may belong to the genus Failleana (that’s a cranidium, the mid-part of a head, on the upper left).

We knew that the Stony Mountain trilobites had been gradually “stacking up”, and volunteer extraordinaire Ed Dobrzanski and I had decided that we would devote some serious time and space to this project when we could. A few months ago the lab was looking relatively clear, so we laid out the hundreds of trilobites in trays and decided which ones were good enough to go into the permanent collection. I identified quite a few of them, but it fell to Ed to carry out the laborious, repetitive work of cataloguing each specimen.

The invaluable Ed Dobrzanski did most of the work on this project.

The specimens were filed away in our collections room.

When he was done, there were some 150 catalogued batches, all neatly laid out and padded. Once I had reviewed his records (we always double-check everything for accuracy!), we still had to find space in the collections, shifting the drawers in several cabinets to free up a block so that the trilobites could all be together and organized.

Finally, last week, we put the trilobites away! This may seem like a very big job for some small old fossils, but it means that many potentially important specimens are now properly recorded and stored, with the trilobites and their data readily available for future research or exhibits.

*These trilobites are almost all incomplete because most trilobite fossils are from pieces of exoskeleton left behind when the animals moulted in ancient tropical seas. For the fossils at Stony Mountain, wave and current action on the ancient seafloor caused further abrasion and breakage.

Left Behind in Airport Cove 

Posted on by Rhiannon Blacher

By Dr. Graham Young, past Curator of Palaeontology & Geology

 

If you think about how Museum paleontologists get fossils, you might guess that we go out and find where the fossils are, extract all of them from the rock and sediment, and return them to the Museum. Certainly that is what we do where fossils are scarce, but in many instances our job really consists of deciding what to leave behind. Our specialists at the Manitoba Museum are called curators, and a curator by definition has to be able to select what is needed for collections and exhibits.

Our field group, walking across dolostone beds in the Silurian part of the cove.  

This fact was really brought home to me in the past couple of weeks, as we revisited sites in Airport Cove, the stretch of shoreline north of the airport at Churchill. Airport Cove covers a large area, with many patches of bedrock spread across the shoreline. These patches of rock allow us to sample many different sedimentary beds from the end of the Ordovician Period and the beginning of the Silurian Period, roughly 445-435 million years ago. 

Landscape view over a rocky stretch of ground leading to the open water in the distance.

In the cove, the rock seems to go on almost forever. 

The rocks in the cove were deposited as sediment in warm tropical seas, so fossils are plentiful in many of them. With such an embarrassment of riches we have to be selective every time we go out in the cove; if I collected every decent fossil, we would need an entire freight train to get them to Winnipeg!  And then, where could we possibly store them?

As a result of our previous work here, many examples of the “standard” fossils from Airport Cove are already resident in the Museum’s collections, and this time we were looking for very specific and rare things. So we would walk around the cove each day, considering and photographing the more common sorts of fossils. Some of these are old friends, on blocks of stone that I can remember being in the same place ten or fifteen years ago. Others were new to me, but I can hope to see them again if I get back here. And then there are the few fossils that are so good that they must go to the Museum; one of these is shown at the end of this piece.

If you are ever in the Churchill area and wish to go looking for fossils, please follow all  guidelines on polar bear safety! We had to leave our work area at Airport Cove twice last week as there were bears nearby, and on one occasion a mother and cub walked right through our site very shortly after we got into the truck.

Northern Exposure – Part 4 (Cataloguing)

Posted on by Amelia Fay
Posted on: Monday August 24, 2015

Guest blog by Jacinda Sinclair, contract Cataloguer and long-time TMM volunteer.

 

In Northern Exposure Parts 1-3, Amelia wrote about her experiences excavating. Now I’m going to cover what happened to her artifacts once she got them back to the Museum.

Cataloguing is a 7 step process.

Step 1 is sorting. To start, I order the artifacts by matching them to the field records made by Amelia’s team. Artifacts found in the same excavation unit are always grouped together.

Step 2 is cleaning. A bucket of plain water and an old toothbrush is usually the way to go.

A spread pile of record sheets with the Government of Manitoba logo on them next to some paper bags, labelled with basic identification details.

Step 1, Sorting: Matching field-bagged artifacts to their record sheets. Sometimes figuring out what goes where can be tricky.

A blue rubber basin with a shallow amount of water covering the bottom, and a toothbrush laid along the upper side.

Step 2, Cleaning: I wouldn’t want to brush my teeth like this, but it’s just fine for artifacts.

A sheet of paper containing columns of catalogue numbers, with a cutting tool, tweezers, small paintbrush, and a jar of sealant placed on top.

Step 3 is identification. This is the hard one. I need to figure out what each artifact is as well as any other information I can gather about how and when they were made. So how do I figure this out? I use a combination of resources: reference books, websites, and the Museum’s own comparative reference collection. This information is entered into a computer database. I also add excavation information from the field notes. The computer assigns each artifact its catalogue number and prints catalogue cards.

Step 4 is labeling. I use a special sealant to glue acid-free labels onto artifacts.

 

Image: Step 4, Labeling: Labeling tools. Until recently, labels were written onto artifacts using fountain pens. It was harder to do and even harder to read.

Step 5 is photography. Photos create an extra record for the assemblage making it easier for archaeologists to do research. Typically not all artifacts are photographed, but if done correctly, anyone looking at the pictures will have a good idea of what the site was like.

Step 6 is conservation. Damaged (rusty) artifacts need special treatment to protect them from further damage. While I might identify which artifacts need conservation, the Museum has a specialist who does the work during this step. The coolest thing about conservation is that sometimes details like maker’s marks are only visible after rust is removed.

Step 7 is storage. Each artifact gets put in a plastic bag with its catalogue card. Everything is filed and placed in climate-controlled storage.

A circular artifact propped up with supports on a surface covered in a grey fabric. A camera is positioned directly above, looking down at the artifact.

Step 5, Photography: Photographs need to be taken from many angles. Getting things into position can be tricky.

Two photos side by side. On the left is a photo of a rusted fish hook. On the right is a close up at one end of the hook where a possible maker mark is mostly concealed by rust.

Step 6, Conservation: Is there the outline of a maker mark on this fishhook? We won’t know for sure until after conservation.

A thin white artifact in a plastic sleeve with an catalogue card identifying is as part of the stem of a pipe. The plastic sleeve is placed on the top of a box filled with similar sleeves.

Step 7, Storage: The end product ready for storage.

That’s cataloguing! Some of the steps sound kind of fussy and boring, but I’m someone who likes to be moving and doing something (even when I’m watching TV), so actually the whole process is pretty relaxing. I love how sites from the same time period and/or area can turn out to be really different from each other. Finding out how each site is unique is the best part of cataloguing.

Broken pieces of pipe stems are common at fur trade sites and don’t usually get as much attention as bowls and spurs, but it’s really impressive to see a complete stem laid out.

Journey to York Factory

Posted on by Amelia Fay
Posted on: Friday August 21, 2015

My last stint of fieldwork this summer had me checking off a box on my bucket list, I finally made it to York Factory! Why did I want to go there so badly? Well, not only is it one of the most important Hudson’s Bay Company sites, it was also the entry-point for early immigration to our province and beyond, I knew I had to see if for myself.

In partnership with Parks Canada, York Factory’s current custodians as it is now a National Historic Site, Kevin Brownlee and I set out with a fantastic videography duo (Kevin and Chris Nikkel) from Five Door Films to try and capture the essence of the site and bring it back for our Museum visitors.

York Factory is located near the mouth of the Hayes River, it’s not the most convenient location for most Manitobans or tourists to visit. That said, the site and surrounding environment is INCREDIBLE so if you ever have the chance to travel up that way, jump on it!

Our journey to the site was just as amazing as the site itself, we opted to travel by boat so we arranged our trip with Clint from Nelson River Adventures. Clint was incredibly helpful with the planning and logistics, and he even arranged our transportation from the Gillam airport to his boat launch.

The Nelson River was very scenic, we went through some rapids, saw eagles flying overhead, and made a quick stop on Gillam Island to inspect a plaque in honour of Thomas Button (the first European to set foot in Manitoba in 1612, and the one to give the Nelson River its name).

The Nelson River is stunning.

As we came to the mouth of the Nelson a bank of fog rolled in, making old Port Nelson look extra creepy. In 1912 the Canadian Government had selected this site over Churchill for their port on Hudson Bay and planned to link it with the Hudson Bay Railway. There were many reasons why this attempt was unsuccessful (too many for this post!) resulting in the abandonment of the site in 1918. Now all that remains is a wrecked dredging ship, and the truss bridge out to a man-made island.

The fog persisted as we emerged into Hudson Bay, and the sea was angry! It was just as I imagined the Bay to be, I would have been disappointed if it was smooth and calm. The boat has to swing out wide into the bay to avoid the shallows of Marsh Point between the Nelson and Hayes rivers. Clint deftly handled the waves while we enjoyed the bumpy ride.

Eventually we made our way around the point and down into the Hayes. Claude and Kyle (Parks Canada site manager and summer student) were waiting for us at the dock and helped us unload all of our gear. We’d made it, and while the journey itself was exciting, we were in for a lot more during our week-long stay!

Perseid Meteor Shower in progress!

Posted on by Scott Young
Posted on: Wednesday August 12, 2015

Every August, our planet passes through a giant dust bunny in space. The dust comes from Comet Swift-Tuttle, a “dirty snowball” that orbits the sun in an oval path. The comet itself is not terribly impressive, but it leaves so much dust in our Earth’s path that the Earth spends several days sweeping up millions of dust particles like a planetary broom. Each piece of dust hits the earth’s atmosphere at incredible speeds, and friction with the air causes the dust to vaporize in a flash of light at altitudes of dozens of kilometers. All the way down here on the ground, we can see each speck of dust’s death throes as a “falling star” or “shooting star”. Astronomers prefer the correct term: “meteor”.

There are actually meteors hitting Earth all the time. On any clear night, if you watch the sky carefully you’ll see a few. Under perfect dark conditions, you can expect 5-10 meteors per hour on just about any night, caused by the random dust particles floating around the solar system. In August, though, Earth hits that dust bunny, and we see many more meteors – a meteor shower. Despite the name, the sky doesn’t fill with shooting stars; you may see one every minute or two, though.

The Perseids are just one of a dozen or more annual meteor showers which are visible. Named for the constellation of Perseus, where they appear to radiate from, the Perseids are the best-known meteor shower because they occur in August, when sitting outside all night in a field is survivable. If you want to get technical, the Geminids of December are a better event, but Manitobans certainly recognize the challenges involved in observing them without losing fingers and toes to frostbite.

Observing the Perseids: Meteor showers are the ultimate low-tech observing event. You don’t need a telescope or even binoculars; your main piece of gear is a reclining lawn chair or blanket. You want to get away from city lights if you can – street lights will make it harder to see the fainter meteors, and really cut down on the number you see. Face the darkest part of the sky, and just look up and watch the stars. Every so often, you will see a meteor streak by.

The shower is active now, but it’s a slow build-up. The peak is on the early morning of August 13th, but you should see meteors for several days before and after that. Meteor showers like the Perseids are always best after midnight – you might not see many in the evening hours. This year, the moon is New on the 14th, and so won’t drown out the meteors with its light.

Fescue Findings

Posted on by Diana Bizecki Robson
Posted on: Tuesday August 4, 2015

As I near the end of my two years of pollinator research in the fescue prairie, I’ve been wondering what it all means. In particular I’ve been thinking about how the pollinator communities in fescue prairies are different than in the tall grass prairies. Here are the patterns that seem to be emerging:

1. Bees are more important pollinators in fescue prairie than flies.

When most people think of pollinators they usually think of bees and butterflies. One of the things I discovered is that flies seem to be more common pollinators than bees in the tall-grass prairie and the reverse true in the fescue prairie. Why is this so? I suspect that it is because tall-grass prairies are in general moister. Many bee species nest underground and if the soil is saturated with water they may not be able to breed successfully. Flies on the other hand breed in a wider variety of habitats (many even have parasitic larvae) and are less affected by moist soils. In fact, fly species that breed in water would benefit from moist conditions.

2. The dominant pollinators may affect plant community composition.

Close up on the top of a breadroot plant where there is a cluster of small white to blue, pea-shaped flowers.

Irregular flowers were more abundant on the fescue prairie, comprising about a third of all insect-pollinated plant species. Further, a greater percentage of visits (~27%) were to the irregular flowers on the fescue prairie. In tall grass prairie, irregularly flowered plants comprise only about a quarter of all species and receive less than 3% of all insect visits. Irregular flowers, particularly those with long floral tubes, are attractive to long-tongued bees and butterflies. Regular flowers with short or no floral tubes are preferred by small bees and flies, which typically (although not always) have shorter tongues. Thus the pollinator community appears to be influencing the composition of the plant community by preferentially fertilizing irregular flowers.

 

Image: The irregular flowers of this breadroot (Pediomelum esculentum) plant are attractive to bees.

3. Insect activity was lower in the spring on fescue prairies than on tall grass prairie.

Close up on a pink flower of a Prickly wild rose.

Bees were more abundant pollinators in the fescue prairie than flies. However in the spring their populations are still small as only the queen bees are out foraging. Bee populations reach their peak in late summer when worker bees are busy collecting nectar and pollen. In contrast, pollinator visits were much higher in the tall grass prairie in spring due to large populations of overwintering flies that hatched once it warmed up.

 

Image: This prickly rose (Rosa acicularis) is visited by flies and small bees.

4. Grazing can alter pollinator activity.

When comparing the pollinator visitation rate between grazed and ungrazed plots over the whole year there was no difference except with respect to timing. The grazed fescue prairie plots had more flowers in spring and early summer and subsequently more insect visitation at those times. In contrast, ungrazed plots produced more flowers in late summer and fall, and experienced more visitations at this time of the year. This suggests that the ideal land management might be a combination of grazing and rest so that a maximum diversity of flowers are available to the pollinator community over the year.

Northern Exposure- Part 3

Boreal forest archaeology is very different from my experiences in the arctic, the biggest thing of course being the trees and massive roots that run through our excavation units. Root clippers quickly became my best friend, but when they fail there’s always the good old chainsaw to take care of a few stumps!

My crew worked hard to try and delineate the post, and half-way through our excavation we realized that the building was not oriented perfectly East-West, but rather on an angle of Northwest-Southeast to the shoreline. We were able to find some remnants of the exterior walls, and the floor boards were fairly well-preserved.

Some wooden floorboards partially visible through uncovered dirt.

Floor boards still visible after all these years!

We didn’t find a ton of artifacts, but we also didn’t excavate the area immediately around the hearth (stone chimney) or the cellar. Perhaps next year we’ll find all the goodies! We did recover enough artifacts for me to get a sense of the date of occupation, it seems like late 18th century but I’ll have a better idea once the artifacts are cleaned up and processed in the lab.

Of course fieldwork is not all-work, I caught my first pickerel (delicious) and on one fishing trip witnessed how quickly a forest fire can spread (scary!). On my way back to Winnipeg I made sure to stop in Thompson to clean my filthy truck, and made a quick side trip to Pisew Falls (highly recommended, it’s gorgeous!).

A forest fire broke out near Barrington River when we were fishing and quickly spread.

Archaeology is dirty business.

Pisew Falls is gorgeous and serene.

I enjoyed my three weeks along the Churchill River, and will post more about the results of our excavation once its catalogued, but my next northern journey will take me up to York Factory so I’d better start packing my gear for another great trip to an AMAZING HBC site.

Shout out to my great crew, thanks for all your hard work in the heat, bugs, and smoke!

Northern Exposure- Part 2

A tightly packed cargo bed of a pick up truck.

Just a few days after coming back from York Landing I was packing up the truck to make the drive back north, only this time I was going back to get my trowel dirty!

As you can imagine, the remnants of the fur trade are all over this fine country and while many of the big sites have been investigated there are hundreds of smaller posts scattered along the waterways just waiting for archaeologists to excavate and learn all about them.

This site was located by local archaeologist Keith Anderson after a forest fire had cleared out a lot of the vegetation, and coincidentally it’s less than 100m away from a post site that was excavated by provincial archaeologist Brian Smith in the 1990s.

Since this post is close to the eroding bank we decided to start work on it this summer. Fortunately for me, Keith and his clearing crew had already done the hard work of removing the dead trees before I arrived (yes, I’m spoiled!).

When a burnt tree messes up your grid, cut it down!

My goals for this season were to determine the limits of the site, by identifying the walls of the post and any related features outside of visible structure, and to acquire enough artifacts to be able to figure out the date of the site. I want to know if it was occupied at the same time as the other nearby post, was it also HBC or their rivals the Northwest Company? There is much to learn from any new archaeological site, and this one will be no different!
